Öğe Classification and standardized reporting of percutaneous nephrolithotomy (PCNL): International alliance of urolithiasis (IAU) consensus statements(2022) Choong, Simon; de la Rosette, Jean J. M. C. H.; Denstedt, John; Zeng, Guohua; Sarıca, Kemal; Mazzon, Giorgio; Saltirov, Iliya; Pal, Shashi Kumar; Agrawal, Madhu; Desai, Janak; Petrik, Aleš; Buchholz, Noor; Maroclo, Marcus V.; Gordon, Stephen; Sridhar, AshwinBackground: To reach a consensus in the classification and standardized reporting for the different types of PCNLs. Methods: The RAND/UCLA appropriateness methodology was used to reach a consensus. Thirty-two statements were formulated reviewing the literature on guidelines and consensus on PCNLs, and included procedure specific details, outcome measurements and a classification for PCNLs. Experts were invited to two rounds of input, the first enabled independent modifications of the proposed statements and provided the option to add statements. The second round facilitated scoring of all statements. Each statement was discussed in the third round to decide which statements to include. Any suggestion or disagreement was debated and discussed to reach a consensual agreement. Results: Twenty-five recommendations were identified to provide standardised reporting of procedure and outcomes. Consensual scoring above 80% were strongly agreed upon by the panel. The top treatment related outcomes were size of sheath used (99.1%) and position for PCNL (93.5%). The highest ranked Outcome Measures included definition of post-operative hospital length of stay (94.4%) and estimated blood loss (93.5%). Conclusions: The consensus statements will be useful to clarify operative technique, in the design of clinical trials and standardized reporting, and presentation of results to compare outcomes of different types of PCNLs.Öğe Consensus statement addressing controversies and guidelines on pediatric urolithiasis(2024) Güven, Selçuk; Tokas, Theodoras; Tozsin, Atınç; Haid, B.; Lendvay, Thomas Sean; Sılay, Mesrur Selçuk; Mohan, Chandra Vamsi; Cansino, Jose Ramon; Saulat, Sherjeel; Straub, Manuela; Bujons Tur, Anna; Akgül, Burak; Samotyjek, J.; Lusuardi, L.; Ferretti, Stefania; Çavdar, Ömer Faruk; Ortner, G.; Sultan, Sajid; Choong, Simon; Micali, Salvatore; Saltirov, Ilya; Sezer, Ali; Netsch, Christopher; de Lorenzis, Elisa; Çakır, Ömer Onur; Zeng, Guohua; Gözen, Ali Sedar; Bianchi, Giampaolo; Jurkiewicz, Beata; Knoll, Thomas; Rassweiler, Jens; Ahmed, Kamran; Sarıca, KemalPurpose: We aimed to investigate controversial pediatric urolithiasis issues systematically, integrating expert consensus and comprehensive guidelines reviews. Methods: Two semi-structured online focus group meetings were conducted to discuss the study’s need and content, review current literature, and prepare the initial survey. Data were collected through surveys and focus group discussions. Existing guidelines were reviewed, and a second survey was conducted using the Delphi method to validate findings and facilitate consensus. The primary outcome measures investigated controversial issues, integrating expert consensus and guideline reviews. Results: Experts from 15 countries participated, including 20 with 16+ years of experience, 2 with 11–15 years, and 4 with 6–10 years. The initial survey identified nine main themes, emphasizing the need for standardized diagnostic and treatment protocols and tailored treatments. Inter-rater reliability was high, with controversies in treatment approaches (score 4.6, 92% agreement), follow-up protocols (score 4.8, 100% agreement), and diagnostic criteria (score 4.6, 92% agreement). The second survey underscored the critical need for consensus on identification, diagnostic criteria (score 4.6, 92% agreement), and standardized follow-up protocols (score 4.8, 100% agreement). Conclusion: The importance of personalized treatment in pediatric urolithiasis is clear. Prioritizing low-radiation diagnostic tools, effectively managing residual stone fragments, and standardized follow-up protocols are crucial for improving patient outcomes. Integrating new technologies while ensuring safety and reliability is also essential. Harmonizing guidelines across regions can provide consistent and effective management. Future efforts should focus on collaborative research, specialized training, and the integration of new technologies in treatment protocols.Öğe Correction: International alliance of urolithiasis (iau) consensus on miniaturized percutaneous nephrolithotomy(2024) Zeng, Guo Hua; Zhong, Wen; Mazzon, Giorgio; Zhu, Wei; Lahme, Sven; de la Rosette, Jean J.

However, because of ongoing uncertainties regarding the optimal perioperative management, operative technique, and postoperative follow-up, as well as a lack of standardization for outcome reporting, consensus is needed to achieve more uniform clinical practice worldwide. Objective: To develop recommendations for RIRS on the basis of existing data and expert consensus. Design, setting, and participants: A protocol-driven, three-phase study was conducted by the European Association of Urology Section of Urolithiasis (EULIS) and the International Alliance of Urolithiasis (IAU). The process included: (1) a nonsystematic review of the literature to define domains for discussion; (2) a two-round modified Delphi survey involving experts in this field; and (3) an additional group meeting and third-round survey involving 64 senior representative members to formulate the final conclusions. Outcome measurements and statistical analysis: The results from each previous round were returned to the participants for re-evaluation of their decisions during the next round. The agreement threshold was set at 70%. Results and limitations: The panel included 209 participants who developed 29 consensus statements on the following topics of interest: (1) perioperative infection management; (2) perioperative antithrombotic therapy; (3) fundamentals of the operative technique; and (4) standardized outcome reporting. Although this consensus can be considered as a useful reference for more clinically oriented daily practice, we also acknowledge that a higher level of evidence from further clinical trials is needed. Conclusions: The consensus statements aim to guide and standardize clinical practice and research on RIRS and to recommend standardized outcome reporting. Patient summary: An international consensus on the best practice for minimally invasive surgery for kidney stones was organized and developed by two international societies. It is anticipated that this consensus will provide further guidance to urologists and may help to improve clinical outcomes for patients.Öğe International alliance of urolithiasis (iau) consensus on miniaturized percutaneous nephrolithotomy(2024) Zeng, Guo Hua; Zhong, Wen; Mazzon, Giorgio; Zhu, Wei; Lahme, Sven; de la Rosette, Jean J. M. C. H.; Choong, SimonOver the past three decades, there has been increasing interest in miniaturized percutaneous nephrolithotomy (mPCNL) techniques featuring smaller tracts as they offer potential solutions to mitigate complications associated with standard PCNL (sPCNL). However, despite this growing acceptance and recognition of its benefits, unresolved controversies and acknowledged limitations continue to impede widespread adoption due to a lack of consensus on optimal perioperative management strategies and procedural tips and tricks. In response to these challenges, an international panel comprising experts from the International Alliance of Urolithiasis (IAU) took on the task of compiling an expert consensus document on mPCNL procedures aimed at providing urologists with a comprehensive clinical framework for practice. This endeavor involved conducting a systematic literature review to identify research gaps (RGs), which formed the foundation for developing a structured questionnaire survey. Subsequently, a two-round modified Delphi survey was implemented, culminating in a group meeting to generate final evidence-based comments. All 64 experts completed the second-round survey, resulting in a response rate of 100.0%. Fifty-eight key questions were raised focusing on mPCNLs within 4 main domains, including general information (13 questions), preoperative work-up (13 questions), procedural tips and tricks (19 questions), and postoperative evaluation and follow-up (13 questions). Additionally, 9 questions evaluated the experts’ experience with PCNLs. Consensus was reached on 30 questions after the second-round survey, while professional statements for the remaining 28 key questions were provided after discussion in an online panel meeting. mPCNL, characterized by a tract smaller than 18 Fr and an innovative lithotripsy technique, has firmly established itself as a viable and effective approach for managing upper urinary tract stones in both adults and pediatrics. It offers several advantages over sPCNL including reduced bleeding, fewer requirements for nephrostomy tubes, decreased pain, and shorter hospital stays. The series of detailed techniques presented here serve as a comprehensive guide for urologists, aiming to improve their procedural understanding and optimize patient outcomes.
